1000+ HP, anyone?

[Ironhorse]

My posting to the thread was not so much concerned with the cost of insurance but more to the change in attitude concerning high horsepower engines. I came home from Vietnam in April of '70 and gas was in the $0.26 to $0.28 per gallon range for 89 octane leaded fuel. There was no US gas shortage until it came about in 1973 with the first oil crunch when OPEC was formed. It is true that the muscle cars fell victim to the higher fuel prices later after the 69-70 production times but the de-tuning and lower compression was the government's push to bring down the horse power available to the masses.

I would still like to know why the change in allowing 800 plus horse power engines in vehicles today regardless of the new tech incorporated in the vehicle when a mere 450 horsepower could not be allowed to continue in production cars from years ago? Again, WTH changed with allowing the horse power ratings made available from the factory today?
